The general rule of thumb is never ever send a rooted set for warranty claim. Unroot it first, then send.

Then you just have to take your chances and send it for warranty. Boot failure can be caused by so many things. If it's due to corrupted internal memory and the only fix is to get it replaced, how would they know whether your device is rooted or otherwise since any evidence storing it is non-functional? Should the boot failure is caused by some other things like a power glitch or the battery connector gone bad, you're unfortunately out of luck. Most probably you'll get charged for the servicing.

The bottom line is if you still have the chance of restoring the phone to its factory condition before sending it for warranty claim, then do it. Dont simply send in a rooted set and expect the manufacturer will keep their end of the deal. They wont and you cant blame them for that. In any case, the day that you decide to root your set should also be the day that you willingly waive all warranty support. You accept that after rooting, you'll never ever need any warranty claim from the phone manufacturer. If you want to root but still have that lingering doubt that someday you might need to send it for warranty, the best thing to do is not to root it.
